If, during service, your brother does anything irregularly, or somewhat negligently, do not become irritated, either inwardly or outwardly with him, but be generously indulgent to his fault, remembering that during your life you yourself commit many, many faults, that you yourself are a man with all infirmities, that God is longsuffering and most merciful, and that he forgives you and all of us our iniquities an innumerable multitude of times. Remember the words of the Lord’s prayer: “And forgive us our trespasses, as we forgive those who trespass against us..”
These words should always remind us that we ourselves at all times are great trespassers, great sinners before God, and that, remembering this, we should be humble in the depths of our hearts, and not be very severe to the faults of our brethren, weak like ourselves; that as we do not judge ourselves severely, we must not judge others severely, for our brethren are – our members just like ourselves. Irritability of temper proceeds from want of self-knowledge, from pride, and also from fact that we do not consider the great corruption of our nature, and know but little the meek and humble Jesus.
